Patented Sept.16,1913.

To all whom it may concern: V

Be it known that we, LOUIS JosnPH EM- MANUEL COLARDEAU, of 13 Rue deNavarin,

professor at the College Rollin, and Jonas RIoHAnn, of 25 Rue Mlingueinstrument maker both in the city of Paris, Republic of France, haveinvented an Improved Display Device, of which the following is a full,clear, and exact description. 1

This invention relates to an operating device applicable to apparatusfor classifying and distributing intended for the examination ofphotographic views particularly stereoscopic views, inwhich the views tobe examined are withdrawn one by one from a box in which they arearranged, lifted to a level with the eye pieces and brought toward themwhich: permits of employing short focus eye pieces.

This apparatus comprises a carriage with horizontal movement supportingthe box in which the views are arranged and capable of advancinguniformly by the distance which separates two consecutive views eachtime the operating mechanism is such a manner that each view is broughtin succession into the plane of a frame with vertical movement; thisframe is intended to lift the view and engage it in a second frame withhorizontal movement which causes it to approach the lenses of thestereoscopic system.

The operating device which actuatesthe parts of an apparatus such asdescribed above is characterized broadly by the fact that the frame withvertical and the frame with horizontal movement are each actuated by aconnecting rod and a crank plate which are given their movementalternately from a single operating crank. .By means of an appropriatedevice the two crank plates can be driven in succession by the drivingcrank. In the preferred embodiment of the invention the driving crankdrives two rings 'rotating together and carrying on half their peripheryonly setsofteeth arranged at an angle of 180 to eachother and able toengage with two separate integral with the two crank plates.

The invention is illustrated but by way of example only in theaccompanying drawing in which:

Figure l is a front elevation of the apparatus with the box containingit and the stereoscopic system removed. Fig. 2 is a corresponding sideelevation. Fig. 3. is a acted upon in I pinions respectively sideelevation on the opposite side to the foregoing. Fig. 4 is alongitudinal section. Fig. 5 is a. detail rear elevation of the framewith vertical movement. Fig. 6 is a similar view to Fig. 4 showing theoperation. Fig. 7 is a side elevation of the operating mecha- .nism.Fig. 8 is a section on the line A A in Fig. 7; Figs. 9'to 13 are detailviews showing the arrangement of the toothed wheels and pinions of themechanism. Figs. 14 to 17 are detail views'showing the means forretaining the views in the frame with horizontal movement.

As shown in the drawing the views a to be examined are contained in abox 2') mounted on a carriage 0 adapted for horizontal displacement onfixed slideways 0 A rack c is fixed to this carriage and meshes with apinion cl (Fig. 4) this pinion is keyed to a shaft al which also carriesa star or Maltese cross wheel 6. This wheelcan be actuated by means of apin f (Fig. 3) intended to engage in the notches in the wheel; this pinis carried by a spring f mounted on a crank plate 9; it passes through arecess in the plate 9, and projects toward the interior.

The bottom of the box I) is recessed in such a manner as to permit ofthe passage of the branches h (Figs. 1 and 4) constituting an extractorand forming part of the frame z with vertical movement; the latter ismovable in slideways i (Fig. 4) it is operated by a lever 6 (Figs. 1 and5) rotating upon a fixed shaft i and a rod 2' pivoted to the crank plate9.

A spring 2' acting upon the lever i balances the weight of the frame 2'.

The frame, y with horizontal movement is guided by rodsj sliding infixed supports 7' '(Fig. 2) it is controlled by arms 1' keyed to arotary shaft j. A connecting rod is is pivoted to one of these arms andalso to a crank plate Z. In each side this frame y' carries a rockingflange m (Figs. 14 to 17) normally maintained horizontal by a spring mthese flanges move aside when inclines m (Fig. 6) carried by thevertical frame 6 come into contact with them.

The crank plate 9 is keyed on a shaft n at the end of which is keyed apinion 0 (Fig. .7). The crank plate Z is rigidly connected with a pinion0 arranged beside theforegoing. These two pinions which are independentof each other mesh respectively with two toothed wheels 20 p integralone with the other and provided with sets of pinions 0 0 1" correspondto one revolution of the wheels 79 79 It follows from this arrangementthat on giving two turns to the handle 8 and consequently to the pinion1" in .either direction (1) the two wheels p 77 make one revolution thepinion 1' meshing in succession with the teeth Q and the teeth 9 I (-2)during half a revolution made by the wheels 29 79 one of the sets ofteeth q or g meshes with one of the pinions 0 0 and causes it to make arevolution and during the other half the other set of teeth 9 or gmeshes with the second of the pinions 0 0 Consequently by rotating thecrank s con-s tinuously the pinions .0 0 make a revolution alternately.The pinion which does not rotate is held absolutely motionless owing tothe circular slots 15 presented by cheeks t (Figs. 12 and 13) integralwith the pinions; j

thecircular edges of cheeks 14 carried by the wheels 29 p engage inthese slots.

The operation of the apparatus is as follows: Assuming that the lastplate examined has just been replaced in the box 7) and that thecarriage c has advanced by the interval separating two views the partsof the apparatus will occupy the position represented in Figs. 1, 2, 3,4 and 5; the frame i for vertical movement is depressed; the frame j forhorizontal movement is brought against it; the rocking flanges m strikeagainst the inclines m and are pressed aside as shown in Figs. 14 and15. If the crank s be then rotated in the direction indicated by the anrow 1 (Fig. 2) in the first place the vertical frame 2' is lifted. Atthis moment the teeth g are in mesh with the pinion 0 the wheel leavingthe position represented in Figs. 7 and 10, half the set of teeth (1come into mesh with the teeth of the pinion 0 causing the latter toeffect a half revolution and during this time the pinion 0 remainsmotionless. The pinion 0 making a half revolution the shaft n and theplate 9 keyed upon this shaft also rotate through a half revolution.This movement of the plate 9 causes the descent of the rod i (Fig. 3,ar-

row 4) the rocking of the lever 71 (Fig. 5)

and the ascent of the frame 2'. In this up ward movement the branches ofthe extractor h lift a plate and cause it to participate in the movementof ascent. This plate engages in slideways 1; (Figs. 4c and 15) in theframe 9', the flanges m being pressed aside allow the plate to engage inthe plate At the end of the upward movement the extremities of theinclines m come opposite the flanges m the latter spring back andassuming the position shown in Fig. 17 support the plate below. Incontinuing to rotate the handle 8 in the same direction the frame 7' isdisplaced "horizontally. This result is obtained by the meshing of thegear p with the pinion 0 which causes the plate Z to rotate in thedirection indicated by the arrow 5 in Fig. 2; the rod presses the arm jin the direction indicated by the arrow 6 which displaces the frame jtoward the left (Fig. 2) and brings it into the position represented inFig. 6. In this position the view is brought closer to the eye pieces;by leaving the handle .9 atrest the view contained in the frame can beexamined for any desired length of time The horizontal displacement ofthe frame j "is produced by a half turn of the plate l by completing therotation of theplate the rod is displaces the frame j in the direction 7(Fig. 6) and applies it against the frame The pivot k of the rod 70presents a certain amount of play in such a manner that in the rotationof the crank s'when the pivot'lc occupies its two extreme positions itissituated in a'certain dead angle; the crank can then be rotated throughthis anglewithout displacing the frame y. then the frame 7' again comesagainst theframe '5 as stated above the flanges m bear against theextremities m y of the inclines of the frame z. By rotating the handle8. still in the same direction the teeth 9 again .act upon the pinion 0,the plate 9 efiects a half revolution and the rod 71 depresses-the framez; from the commencement ofthe movement the inclines m de press theflanges 47?; in such a manner that the plate is no longer retained inthe frame j and rests upon the'branches hfthe plate descends with theframe '5 and resumes its 3 place in the box I). At the end of thismovement the pin f engages in a notch in the wheel 6 and causes it torotate to the extent of one division. The pinion cl then causes theracks and the carriage c to advance by the amount of the intervalcomprised between two successive views, in such a manner that byrepeating the operations that have just been described the'followingplate is brought in front of the eye pieces and so on in succession. p rV The novel device is very simple and strong. It presents the advantageof operating silently in both directions on rotating It is possible tocommence a movement, to interrupt it, to go back and so forth withoutany difiiculty.

When all the views have been examined the carriage c has reached the endof its movement. The views can then be examined in reversing thedirection or the carriage can be brought into its initial position bythe handle 8 in one direction or the other.

disengaging it from the driving mechanism M in any convenient manner.

The arrangements described are no applicable to apparatus for examiningviews but also to similar devices intended for projecting them.

The arrangements indicated above are given by way of example only andthe forms, dimensions and detail arrangements can vary in every casewithout affecting the principle of the invention.

We claim:

In a classifying and distributing apparatus for photographic views, abox in which the views are arranged, a horizontally movable carriagecarrying said box, a vertically movable frame for lifting successivelyeach view, eye pieces, a horizontally movable frame for bringing saidview near the eyepieces, a connecting rod and crank plate device foreach frame, pinions respectively connected with the crank plates, asystem of two toothed wheels connected together and provided with teethon one half of their periphery said pinions engaging with said firstmentioned pinions, an operating crank and a pinion for simultaneouslyactuating the two toothed wheels.
